				<div class="class-description"><p>A special render pass node that renders the scene with SSAA (Supersampling Anti-Aliasing).
This manual SSAA approach re-renders the scene ones for each sample with camera jitter and accumulates the results.</p>
<p>This node produces a high-quality anti-aliased output but is also extremely expensive because of
its brute-force approach of re-rendering the entire scene multiple times.</p>
